Title: Cutter head for suction dredge - has struts supporting blades between radial spokes and back ring and scoop plates on spokes
Inventor: PROEHL NORMAN P
IPC: E02F9/28
Filed: 1977-08-04
Abstract: The cutter head includes a hub with radial spokes and a back ring of greater radius than the spokes. Struts extending between the spokes and the back ring are connected to the spokes at the outer ends and to the back ring near the periphery to form a truncated conical structure. Blades mounted on the struts are inclined in the direction of rotation of the cutter head. Radial scoop plates are mounted on the spokes at the leading edges, and inclined in the direction of rotation of the cutter head. Their outer ends abut and connect with the forward ends of the strut blades to form L-shaped digging members.

Title: Non-blocking tennis net - uses light beams and photoelectric cells giving visible or audible signal when ball intercepts beams
Inventor: LOEFFELHOLZ EBERHARD
IPC: A63B61/00
Filed: 1977-11-16
Abstract: A net for a tennis court uses beams of light instead of strings. The net has two posts which are joined by a tensioned cable to form the upper edge of the net. One post has a row of lamps or devices to emit electro-magnetic radiation. These beams fall on a matching row of photo-electric cells on the opposite post. When a ball passes through the 'net' it intercepts one or two beams. The photo-electric cells form part of circuit which emit visible or audible signals when the beams are intercepted.

Title: Counting and display device for telephone metering pulses - has two operational amplifiers connected in cascade with adaptor at input of one of them
Inventor: GOETZ JUN RUDOLF
IPC: H04M15/28
Filed: 1978-02-11
Abstract: An electro-magnetic adaptor or filter is positioned in the dispersion field of telephone subscriber's appts.

Title: Milling cutter for cutting chamfers - has eccentric mounting in screwed bush for ease of adjustment of depth of cut
Inventor: HOLDERRIED JOSEF
IPC: B23C3/12
Filed: 1978-03-10
Abstract: The milling cutter (2) is used for cutting chamfers on the edges of square workpieces (4). The workpieces are supported by two inclined plates (17) (18) so that the initially sharp edge of the workpiece, projects between the lower edges of the plates. The milling cutter is mounted on a shaft which runs in an eccentric bush (5) with a screwed end (6). a knurled surface (8) enables the bush to be rotated and move axially because of the thread. This enables the depth of cut to be adjusted and also spreads the wear over the whole width of the cutter.

Title: Surgical instrument for taking samples from intestines - has cutter near entry hole for tissue operated by liquid pressure
Inventor: HENDRICKSE RALPH GEORGE
IPC: A61B17/30
Filed: 1978-05-30
Abstract: To take samples from the interior of the intestines, a surgical instrument is inserted inside the body of the patient, operated with a cutting action by remote control. The end of the instrument consists of a closed tube (10) containing a knife (22) whose action is controlled by a flow of e.g. a saline solution fed from the remote control point. The closed end is divided by a partition (14) down the middle, terminating short of the end, to form a supply path (16) and return (18). This forces the knife body (22) upwards so that its cutting edge (30) severs the portion of the intestine which protrudes through a hole (34) in the housing, near the closed end.

Title: Operating bottom pour stoppers on metallurgical vessels - where sliding stopper plates are driven by work cylinders using pressurised water as the hydraulic fluid instead of oil
Inventor: STADTFELD GERHARD
IPC: B22D41/38
Filed: 1978-07-31
Abstract: The sliding plate in each stopper is connected to a piston; and each piston is actuated in a hydraulic cylinder by purified water at 160-300 bars, which is used as the hydraulic fluid. The pref. pressure generating sytem consists of a water tank using motor-driven pumps to feed the water into >=1 compressed air reservoir, from which the water is driven through a network of valves to the hydraulic cylinders. Pref. the pressure generator consists of compressed air reservoirs fed with air from a compressor fitted with a dryer or ultra-filter for the air, which is fed from the reservoirs to an air/water pressure transducer. The system is used esp. on continuous casting plant. The use of water as the hydraulic fluid eliminates the danger of fire, explosion or injuries which can occur when oil is employed as the hydraulic fluid.

Title: Tracking control for agricultural trailer - includes ground monitoring disc linked to drawbar servo mechanism
Inventor: SCHULTE WERNER
IPC: B62D13/00
Filed: 1978-08-05
Abstract: The agricultural trailer, with working attachments, is accurately gided along the plant rows by a sensor (20) as well as by a disc (10) which tracks in the ground. The disc is linked to a steering servo valve and ensures that no sudden deviations are made due to gaps in the plant row or ground irregularities. The disc provides a simple tracking control to maintain the alignment of the trailer. The rear wheels of the trailer are steered by the servo control so that the lateral position of the vehicle is ensured.

Title: Slide fastener manufactured from a single tape - by moulding integral coupling members from a central thermoplastic section
Inventor: WANCKEL MATTHIAS
IPC: A44B19/14
Filed: 1978-10-25
Abstract: A process for the manufacture of a slide fastener in a single operation commences with a textile tape which is divided into three sections by means of two warp threads of heavier count than the rest, >=1 of the sections, pref. the central one, consisting entirely of synthetic material. This section is heated to the melting point of the material, which is moulded into the shape of coupling members between two heated continuous belts with profiled surfaces, and the tape is then folded longitudinally along the centre line of the moulded section to form a fastener stringer. The fastener has extremely small members which are integral with the tape, and cannot become detached. The fastener is formed in a single operation, and is easily attached to a garment.

Title: Extrusion die, esp. for mfg. hollow aluminium alloy profiles - where short mandrel is accurately centred in die bore, esp. for mfg. tubes
Inventor: PUEHRINGER SIEGFRIED
IPC: B21C25/00
Filed: 1978-11-07
Abstract: The die consists of two parts, viz. an outer die contg. one or more holes forming the periphery of the extrudate; and screwed into die is a bridge contg. one or more inlet chambers adjacent to the extruder barrel. The base of the inlet chamber is formed by the rear end of a mandrel and the sloping surfaces of webs which join the mandrel to the outer ring section of the bridge. The inlet chamber pref. increases in dia. away from the extruder barrel, and then tapers towards the rear end of the mandrel; and the bridge pref. forms three holes leading to a ring cavity surrounding the front end of the mandrel. This design of die prevents changes in the cross-section dimensions of the extrudate (e.g. a tube) during the extrusion process; and the die has long working life.

Title: Synthetic fibre sliver mfr. - by drawing filaments for direct cutting-tearing into a staple fibre sliver
IPC: D01G1/10
Filed: 1978-12-22
Abstract: To mfr. cable strand of synthetic fibre filaments, untreated continuous filaments are first drawn to make them suitable for use. They are then cut or pulled apart without intermediate dwell time. Filaments are spun continuously to give sliver which is drawn, torn or cut and then laid into ordered and paralleled sliver form. Continuous filaments are given a cable ending by light crimping action, before they are torn or cut, or filaments can be crossed within the cable to give an ending. Additive, such as brightening agent, can be used to give the cable ending. a tearing machine or a cutter is mounted directly after the drawing unit to convert the material into a staple fibre sliver. System provides continuous and economic process, without damaging the fibres by melting or mechanical distortion.
